TO ALL WHOM IT MAY CONCERN: Y

Be it known that I, HENRY MEYER, ot' Grafton, in thecounty of Ozaukee, and State of Wisconsin, have invented a new and improved Machine for Making Chair-Seats; and I do hereby declareV that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of Athis specification.

Figure l represents a vertical longitudinal section of my improved machine for making chair-seats.

Figure 2 is a vertical transverse section of the'same.'

Figure 3 is a plan or toplview of the same.

Similar letters of reference indicate corresponding parts.

This invention relates `to a new machine for hollowing the upper surface of wooden chair-seats, and consists in the combination of a carriage, sliding on prepared rails, witha set-screw, by means of which the depth of the depression jwill be regulate-dr and with revolving cutters, which can. be easily removed from. the head, to be replaced by others of different shape, whenever desired.

The machine is so arranged that chair-seats of different shapes can be fitted thereon.

A, in the drawing, represents the Vframe of my improved machine. The same is made'of wood, metal, or any other suitable material, of suitablesize and shape. In it are the bearings for a horizontal driving-shaft, B, which receives rotary motion `from suitable mechanism.

Onthe shaft B is mounted a cutter-head, C, on which cutters D are fastened, by means of screws a a, in such a, mannerthat they can be easily removed. The cutting-edgesof the cutters D are made convex, as shown in fig. 2, so that they will cut the required cavity easily in the face of-the sea-t.

On the sides ot` the frame A are arranged parallel rails, E and F, the one straight and horizontal, the other, F, with a7 concave portion opposite the cutters, as is clearly shown in iig. 1.

G represents a carriage, resting 0n the rails E F, and adapted for holding the seat to be planed. iThe carringe isprovided with a lever, H, for holding down the seat G', said lever being hinged to it, as indicated in fig. 3. By means of set-screws, I: b, the position of the seat on the carriage can be regulated. l

rihe support of the carriage on the rail F consists of a. set-screw, c, iitted into the under side of the carringe, as shown in igs. 1 and 2. By making the screw c project more 'orless from the carriage, the cavity cut into the scat can be,made more or less shallow, and of lesser or greater length.

By the concave track F, the seat is i'ed so that the cavity will taper oit` towards the-sides.

lhe carriage is moved by hand, or otherwise, sc that the seat will be fed above the cutters, which, by the shape of their cutting-edges, determine the form of the cavity cut into the lower 'face of the seat,.which is the upper face of the same when attached to a chair.

Having thus described my invention, I claim as new, and desire to secure by Letters Patentlhe guides E F, the latter provided with the concave upper edge, whereby, as the carriage G is reciprocated, a rising and falling motion is imparte-d to it, by which the depression in the chair-seat is cut, all arranged and operating as described.

HENRY MEYER.
